Drought, Reduced Snowpack, and High temperatures force Pioneer Irrigation District to Reduce Deliveries:

7/14/2021 Update:
Based off current conditions Pioneer Irrigation District has further reduced its deliveries out of reservoir storage to 70%. As patrons continue to see reduced deliveries, we are constantly monitoring the situation in hopes to stretch the 2021 water season to approx. September 7th, 2021. If you have questions or concerns about the reduction, please call Pioneer Irrigation Superintendent, Mark Zirschky at (208) 459-3617.

A reduced snowpack coupled with drought like weather, including an extended amount of record high temperatures has forced Pioneer Irrigation District to reduce water deliveries by nearly 20 percent, compared to the amount of water it normally supplies to its 5,800 patrons. Unless conditions dramatically improve, Pioneer Irrigation District could be forced to further reduce its deliveries or end its irrigation season completely in late August/early September, more than a month earlier than normal.


Pioneer Irrigation District is hopeful the remaining natural flow will hold steady, and demand will decrease, which will decrease the amount of storage water being diverted to its patrons. Pioneer Irrigation Water Superintendent, Mark Zirschky, stated the excessive record setting heat we have experienced the last several days, has required above normal delivery rates, to keep crops and residential lawns and gardens from damage and/or complete loss. The Cities of Nampa, Caldwell, and the Caldwell Lateral District have been working alongside us to reduce delivery rates to residential areas, in an effort to stretch our current water supply.


"We will be running the system as lean as we possibly can. In addition, we also need the cooperation of our users to be as conservative as possible. The recent heat that we have experienced, along with the higher temperatures in the forecast, has caused us to reduce deliveries to a point of balance between irrigation supply and irrigation needs", said Board Chairman Alan Newbill.


Conditions could change, should the temperatures drop and demand decrease. Pioneer Irrigation District will be monitoring the current conditions closely to determine if further adjustments are needed in an effort to make the 2021 irrigation season as beneficial as possible.
